This reduces overhead of mutex locking and increases context switch
rate significantly (which helps to measure and profile the context

Recently there have been several reports of applications SEGV'ing

In P9, OCC(On Chip Controller) can be sent commands inband via shared
memory based command response interface. This patch adds a platform
driver to support the OCC command-response interface.
The skiboot patch for the interface is posted here:
https://lists.ozlabs.org/pipermail/skiboot/2017-June/
This patch adds support to get a unique token for async completion
requests. This will be used for creating non-repititive request
handles for consecutive requests in OPAL-OCC command/response
interface.
